The would-be robber allegedly walked into Eastern Bank in South Boston Thursday and gave the teller a note that said: "Give me all your money," The Boston Globe reported.
The teller refused and said the window was closed, police said.
"Then he moved over to the next teller and they scolded him for getting in front,'' police spokesman Eddy Chrispin told the newspaper.
The second teller and a customer in line told the man he had to take off his hoodie and wait his turn in line, the newspaper said.
The suspect refused to take off the sweatshirt and left the bank.
No one at the scene was injured, and there was no weapon shown.
Police said they were investigating the attempted robbery.
